Edward J. – Repair or Service a Central Air Conditioning System Comments: Carlos completed a seasonal tune-up for the a/c system in two of our rental homes. He gave my wife and I a thorough explanation of the results. Fortunately, we did not have any issues that required immediate attention. He gave recommendations for issues that would require attention in the near future. My wife and I were very pleased with his professionalism and we plan to use this company for our future a/c needs.
